Abstract
A metal sheet pile comprises a cold formed wall section to the longitudinally extending side edges of which are secured hot formed clutch sections (12). The clutch sections (12) may be produced by hot rolling, extrusion or other hot forming process and are preferably welded to the side edges of the pan or web by, for example, laser, submerged arc or resistance welding. Cold forming of the wall section from steel plate may be effected in a press, or by passing steel plate between or around cold bending rolls.
